It carries the ANSI insert code DNMG432 and ISO code DNMG150408, featuring a 55-degree diamond (rhombic) shape with a negative rake and neutral hand orientation. The AC8025P grade delivers high-to-moderate wear resistance when cutting steel and moderate wear resistance and toughness when cutting cast iron. With a 0.5-inch inscribed circle and a 0.0313-inch corner radius, this insert is sized for light machining and finishing operations where dimensional accuracy and surface finish are priorities.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing and light machining passes on steel and cast iron workpieces in both production and job-shop turning environments. The ESX chip breaker geometry is optimized for controlled chip flow at light depths of cut and moderate feed rates, making it appropriate for close-tolerance turning on parts where surface integrity matters. It is held using a clamp or pin mounting method and fits standard DNMG-style toolholders. The DN series designation follows ANSI and ISO 13399 standards, making it straightforward to cross-reference into existing tooling inventories.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC8025P CVD-coated carbide grade for high wear resistance on steel (P) and toughness on cast iron (K)\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (ANSI D shape code) with negative side clearance and negative rake for stable, rigid cutting\u003c\/li\u003e\n  \u003cli\u003eESX chip breaker geometry optimized for finishing and light machining operations\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation allows use in both left-hand and right-hand toolholder setups\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards for straightforward toolholder compatibility verification\u003c\/li\u003e\n  \u003cli\u003eClamp or pin insert holding method supports secure seating under interrupted and continuous cut conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard DNMG-style turning toolholders that accept a 55-degree diamond insert with a 0.5-inch inscribed circle, 3\/16-inch insert thickness, and clamp or pin holding.

Ensure the toolholder pocket and seating surfaces are clean and free of chips before seating the insert. Use the correct clamp screw torque as specified by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and will crack under excessive clamping force. Inspect the insert for edge chipping after each indexing cycle and before returning the machine to production.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG150408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code (Full)\u003c\/strong\u003e: DNMG150408N-SX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC8025P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6102 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Coated — CVD Process\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ESX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing and Light Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Cast Iron (K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19P7BEW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51736900436274,"sku":"19P7BEW","price":283.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bb853e91b2d0f0ce0df20364f7303ab.jpg?v=1788781700","url":"https:\/\/voomisupply.com\/products\/sumitomo-19p7bew-turning-insert-dnmg432esx-ac8025p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
